Built to DIN 6537L standards, it features a 140-degree split point (SU point type) with web thinning for self-centering entry and reduced thrust. The bit carries a FIREX coating for heat and wear resistance. With an overall length of 103 mm and a 25\/64-inch (0.3906-inch) cutting diameter, this is a production-grade tool suited for machinists, toolroom technicians, and maintenance professionals working on tight-tolerance applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for cast iron and steel workpiece materials, making it a practical choice for machine shops, fabrication operations, and industrial maintenance environments. The 5xD flute-to-diameter ratio provides a flute length of 61 mm, supporting deeper hole depths up to 46.12 mm (1.816 inches). The straight-cylindrical shank with a 10 mm shank diameter and 40 mm shank length fits standard drill chucks and collet holders without modification. It is sold individually and intended for use in CNC machining centers, drill presses, and hand-held power tools where carbide tooling is appropriate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eFIREX coating reduces heat buildup and extends tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point with web thinning enables self-centering entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute geometry promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6535 and DIN 6537L standards for consistent dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to 0.006 to 0.021 mm for repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 6537L Series 5515 jobber-length drill bit compatible with standard straight-cylindrical chuck and collet systems accepting a 10 mm shank.

Confirm the machine spindle is at a complete stop before changing tooling. Follow the tool manufacturer and machine manufacturer guidelines for recommended speeds and feeds when drilling solid carbide tooling in ferrous materials. Inspect the cutting edge and FIREX coating for chipping or wear before each use, as carbide edges are brittle and sensitive to side loading or interrupted cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 25\/64 inches (0.3906 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 103 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 61 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 46.12 mm (1.816 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: SU (Self-Centering)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.006 to 0.021 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5515\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9055150099200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51729607917874,"sku":"9055150099200","price":261.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7a011e334b6e0cfd7c233ace7256d4a_7ab60f29-055c-4701-a5d1-ebbdf5daaae0.jpg?v=1788706699","url":"https:\/\/voomisupply.com\/products\/guhring-9055150099200-carbide-jobber-drill-bit-25-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
